SHELL FOR oARBlD-CARTRIDGES.

SPECIFICATION forming part of Letters Patent No. 634,402, dated October 3, 1899.

Original application filed January 7, 1899, Serial No. 701,479. Divided and this application led March 7,1899. Serial No.

. 708,127. (No model.)

.To LZ/Z whom it may concern:

Be it known that I, DENNIE M. DORMAN, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented new and useful Improvenients in Shells for Carbid-Cartridges, of which the following is a specification.

My invention relates to an improved shell for carbid-cartridges.

The object of my invention is to provide an improved shell for containing a given quantity of carbid which shall permit the carbid to be readily attacked by the water when the cartridge or shell containing the carbid is dropped or submerged therein.

A further object of the invention relates to improved means for retaining the carbid within the shell.

In order that the objects of the presentinvention may be more clearly understood, reference may be made to my application, Serial No. 701,479, filed January 7, 1899, of which the present case is a division, wherein is shown and described a gas-generating apparatus in which a number of carbid-cartridges, such as form the subject-matter of the present case, are arranged in a chute, and means are provided for discharging these cartridges successively into the water of the generatingchamber. It is for such or an analogous application that the subject-matter of the present invention is intended.

I have illustrated my invention in the accompanying drawings, in which- Figure 1 is a perspective view of my improved shell, and Fig. 2 is a longitudinal sectional view through a cartridge.

The reference-numeral 1 indicates a metal or other cylinder having open ends and designed to have packed therein a body of carbid 2. After the cylinder has been packed with carbid its ends are closed by means of metal or other disks 3, one of which is inserted in each end, and which disks are of a size to be held in the cylinder by frictional engagement therewith. These disks are connectedl to opposite ends of a chain 4, extending through the cylinder 1 and somewhat longer than said cylinder, and each diskis provided with an aperture 5, through which water can enter to the carbid in the shell.

The operation is as follows: As the water contacts with the carbid in the shell the gas generated will blow the disks out of the cylinder,thus permitting the free and full contact of the water with the carbid; but the chain 4 will hold the disks and prevent them from being mechanically disconnected from their cylinder. Thus the shell, comprising the cylinder 1 and the disks 3, connected by the chain 4, can readily be removed from the generatingchamber and the shell be used for a fresh supply of carbid. The shell with the carbid therein I term a cartridge.

While my improved shells will preferably ybe constructed of metal, I do not wish to limit my invention to the use of any particular ma= terial, as there are other substances of which the shells could be made, such as suitablyprepared paper, cardboard, or the like.

Having thus fully described my invention, what I claim as new is- 1. A cylinder containing carbid and having open ends and apertured disks held in said open ends by frictional engagement with the shell and adapted to be expelled therefrom by gas generated by the carbid when the shell is submerged in water, substantially as described.

2. Ashell for supplying carbid to the generating-chamber of an acetylene-gas generator, comprising a cylinder having open ends, apertured disks designed to be inserted in said open ends and retained therein by frictional engagement with the shell and a relatively long chain extending through said shell and connected at opposite ends to said disks, substantially as described.

3. As a new article of manufacture a carbid-cartridge comprising a cylinder having carbid packed therein and closed at opposite ends by connected, removable apertured disks.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

DENNIE M. DORMAN.
